Hello this sounds like the internal mixing flap/ blend door thats inside the dash ducting is stuck in the hot position?the hot and cold air are mixed in a chamber just after the heater matrix and fan assembly in a box behind the center vents I'd suggest that the next step will be to strip the dash out so this motor / mixing flap can be accessed but its also worth trying this reset procedure for the climate control unitSelect full cooling (Lo)• Select full heating (Hi)• Back to full cooling• Select face followed by floor• Then select face again• Finally select defrost and to run the diagnostic on the unit1 Simultaneously hold AUTO and RECIRC, switch ignition on - display element check.2 Press AUTO - display of stored fault (numeric) code, if zero appears there are no stored codes3 Press Face - scroll through stored faults ( max 5)4 Simultaneously press Face and R - clear stored fault codes (may need to be repeated for each fault)5 Press Recirc (press FAN to skip actuator check) - initiate actuator check (actuator codes 20-27)6 Press FAN - exit error check mode the attached PDF has the error codes
